The first half of the Communion liturgy is now covered by the Saint Aelfric Customary. You may already have seen the prologue on how to choose between the two Communion Rites in the 2019 Prayer Book, and now the first half of the actual worship service is summarized.
There is clarification on the use of the Acclamations at the very beginning, ideas about the Collects, guidelines for including the Decalogue periodically, notes about handling the lessons, and even some of the music around them.
Notes on parts of the liturgy that are often taken for granted or ignored (the Gloria, the Creed, the Prayers of the People, the Exhortation) may also give you pause for thought. And, perhaps most unexpectedly, we’ve got a recommended use of the full list of Offertory sentences. Just think how few of them are normally read, and how many of them sit unused, unheard by the majority of our congregants!
